Constructor Detail

### SkeinParameters.Builder

    public SkeinParameters.Builder()

### SkeinParameters.Builder

    public SkeinParameters.Builder(java.util.Hashtable paramsMap)

### SkeinParameters.Builder

    public SkeinParameters.Builder(SkeinParameters params)

Method Detail

### set

    public SkeinParameters.Builder set(int type,
                                       byte[] value)

  Sets a parameters to apply to the Skein hash function. Parameter types must be in the range 0,5..62, and cannot use the value `SkeinParameters.PARAM_TYPE_MESSAGE` (reserved for message body).

  Parameters with type < `SkeinParameters.PARAM_TYPE_MESSAGE` are processed before the message content, parameters with type > `SkeinParameters.PARAM_TYPE_MESSAGE` are processed after the message and prior to output.

  Parameters:
    `type` - the type of the parameter, in the range 5..62.
    `value` - the byte sequence of the parameter.
  Returns:
    the current builder instance.

### setKey

    public SkeinParameters.Builder setKey(byte[] key)

  Sets the `SkeinParameters.PARAM_TYPE_KEY` parameter.

### setPersonalisation

    public SkeinParameters.Builder setPersonalisation(byte[] personalisation)

  Sets the `SkeinParameters.PARAM_TYPE_PERSONALISATION` parameter.

### setPersonalisation

    public SkeinParameters.Builder setPersonalisation(java.util.Date date,
                                                      java.lang.String emailAddress,
                                                      java.lang.String distinguisher)

  Implements the recommended personalisation format for Skein defined in Section 4.11 of the Skein 1.3 specification.

  The format is YYYYMMDD email@address distinguisher, encoded to a byte sequence using UTF-8 encoding.

  Parameters:
    `date` - the date the personalised application of the Skein was defined.
    `emailAddress` - the email address of the creation of the personalised application.
    `distinguisher` - an arbitrary personalisation string distinguishing the application.
  Returns:
    the current builder.

### setPersonalisation

    public SkeinParameters.Builder setPersonalisation(java.util.Date date,
                                                      java.util.Locale dateLocale,
                                                      java.lang.String emailAddress,
                                                      java.lang.String distinguisher)

  Implements the recommended personalisation format for Skein defined in Section 4.11 of the Skein 1.3 specification. You may need to use this method if the default locale doesn't use a Gregorian calender so that the GeneralizedTime produced is compatible implementations.

  The format is YYYYMMDD email@address distinguisher, encoded to a byte sequence using UTF-8 encoding.

  Parameters:
    `date` - the date the personalised application of the Skein was defined.
    `dateLocale` - locale to be used for date interpretation.
    `emailAddress` - the email address of the creation of the personalised application.
    `distinguisher` - an arbitrary personalisation string distinguishing the application.
  Returns:
    the current builder.

### setPublicKey

    public SkeinParameters.Builder setPublicKey(byte[] publicKey)

  Sets the `SkeinParameters.PARAM_TYPE_KEY_IDENTIFIER` parameter.

### setKeyIdentifier

    public SkeinParameters.Builder setKeyIdentifier(byte[] keyIdentifier)

  Sets the `SkeinParameters.PARAM_TYPE_KEY_IDENTIFIER` parameter.

### setNonce

    public SkeinParameters.Builder setNonce(byte[] nonce)

  Sets the `SkeinParameters.PARAM_TYPE_NONCE` parameter.

### build

    public SkeinParameters build()

  Constructs a new `SkeinParameters` instance with the parameters provided to this builder.
